Be it known that I, JOHN D. KENNEDY, a citizen of the lJnlted btates of America, residing at New Kensington, 1n the county .of estmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Demountable Rims, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to detachable tires for vehicle wheels, and the primary object of my invention is the provision of novel means for converting a wheel having a metallic tire into a wheel having a resilienttire, whereb y a. wheel that is ordinarily God for drayage purposes can be used in connection with a pleasure vehicle, as a carriage.

Another object of this invention is to provide a demountable resilient tire holder or rim that can be'easily and quickly placed in position upon the tire of an ordinary wheel and positively retained thereon, the demountable resilient tire being secured in a manner that adds strength and ri idity to the wheel upon which it 18 mounts A further object of this invention is to provide a demountable resilient tire for wheels consisting of comparatively few parts, inexpensive to manufacture, easy to install and highly efiicient for the purposes for which they are intended.

These and such other objects in View as i may hereinafter appear are attained by a mechanical construction that will be hereinafter specifically described and then claimed,

Reference will now be had to the drawing, wherein Figure 1 is a side elevation of a' portion of the wheel partly broken away .and partly in section, Fig. 2 .is a perspective View of the confronting ends of the resilient tire holder, and Fi 3 is a cross sectional View of a portion of a wheel provided with'the tire holder. 3

The reference numeral 1 denotes a/por tion of a hub having spokes 2, a felly 3 and a metallic rim or fire. a, these elements constituting the ordinary typeof wheel.

The demountahle rim comprises a metallic channel-shaped holder having a flat bottom 5 and the side walls 6 thereof provided with enlargements or reinforcements 7 to. add rigidity to the side walls without impairing the resiliency of the demountable rim. The

de'm'ountable rim which when "in: operative position 'is arranged circumferentially of the wheel rim 1 and one end of the demount;

tongue 8 which is adapted to ;tit"bet-we en'the side Walls 6 of the opposite end 'ofthe demountable rim and rest upon the bottom bf the said rim 5. The tongue, 8.-is provided with a longitudinal slot 9 and s id tongue is retained in engagement with the opposite end of the demountable rim by atrivet 10 eX- tending through the slot 9.- The head of the rivet is flattenedafter the tongue 8 is placed in osition, and itis by virtue of the slot 9 tlet the ends of the dem o-untable rim can shift, as will presently appear. Mounted in the demountable rim 5 and frictionally held therein is a resilienttire 11, preferably made of solid rubber, said tire projecting above the-side walls 6 of the demountable rim.

To clamp the demountable rim'upon the wheel rim 4, a specially designed instrument is employed. to expand the demountable rim at the confronting ends "thereof. The instrument is constructed" upon the principle of a turn-buckle and comprises a hub head 12 having a shank 13 for a r0- tatable buckle 14.. Ad'ustably mounted in the upper end of the huckle is a screw'15 carried by the shank 16 of a holder head 17. The heads 12- and 17 are segment-shaped to conform to the curvature of the hub 1 and the holder 5, and the demountable rim, and the head 17 is made of thin plate, whereby it can engage eithey of the shoulders 18 formed by making the holder 5 of a greater Width than the rim'4, as best shown in Fig. 3 of the drawing. =VVhen the ends of the demountable rim are clamps upon the rim 4,. The movement between t e ends'ofthe .demountable rim is very slight, but it is 'suihcient to cause the demountable rim to frictionally engage the rim. To further clamp the demountable rim upon the rim 4,

'demountable'rim are forced apartby the turn buckle, the remaining portions of the a plurality of U-shaped clips or clamping Wheel rim.

tion the ordinary stay bolts 21 of the Wheel 1 are employed, these stay bolts retaining the rim 4: upon the telly and in order that-the bolts can be used for holding the clips, said bolts are made of greater length whereby they will extend through openings 22 pro vided therefor in the clips and receive nuts 23. After the clips are placed in position, the turn buckle employedfor expanding the demountable rim can be removed.

The resiliency of the demountable rim is sufficient to retain the demountable'rim in position upon the rim 4 until the expanding tool is placed in position to clamp the de mountable rim upon the rim, and the expanding tool retains the demountable rim in position until the clips aremounted upon the telly of the wheel to engage the demountable rim.

To remove the demountable rim it is only necessary to removethe nuts 23. When the clips 19 are released the demountable rim retracts and can be easily removed from the.

It is apparent from the foregoing that the resilient metallic demountable rim will add strength and rigidity to the Wheel When clamped to the Wheel rim 4:, and that sufficient rubber is used in the tire 11 to insure a cushioning of the wheel when in motion.

It is to be understood that the invention A demountable rim comprising a split channehshaped member" having squared ends and adapted to receive a resilient UTJQ.

and further adapted to be detachably posi- 'tioned circumferentially with respect to a heel rim, a tongue formed integral with and projecting from one end of the bottom of said member, said tongue offset out- Wardly With respect to the outerface of said bottom and adapted to project upon the outer face of the bottom of said member at the other end thereof, said tongue provided at its free end With a longit-udinal slot, and

an outwardly projecting headed stud carried by that end of the bottom of the free end of the tongue and extending through the slot for connecting the ends of the member together, one end Wall of said slot limiting the movement of the ends of the member away from each other.-
